Finding dirt in one's ear after ghusal

Please advise. I performed my ghusl as per usual. About an hour later I found some “dirt” in the crevice of my ear, like maybe old skin cells or maybe like the texture of tears once it has dried up. Is my ghusl counted? My concern is that the water did not pass over the area where the “dirt” was found and as such my ghusl might not be counted. Please advise.
